Looks pretty good to me (looking at version 1.19). One comment is that, in the 'optional extensions' section, where you say 'such mistakes are easily diagnosed', you could point to your generator wrapper as an example where attempting to reuse the block handler raises a RuntimeError on the second attempt. Also, I'm wondering if it would be useful to have a 'closing' template that looked like: @with_template def closing(obj): try: yield obj finally: obj.close() That can be used to deterministically close anything with a close method, be it file, generator, or something else: with closing(open("argument.txt")) as contradiction: for line in contradiction: print line with closing(some_gen()) as data: for datum in data: process(datum) Cheers, Nick. -- Nick Coghlan | [EMAIL PROTECTED] | Brisbane, Australia --------------------------------------------------------------- http://boredomandlaziness.blogspot.com _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
